ISIL weapons found in Denmark

Police discovered guns and ammunition after the arrest of four suspects.

Danish authorities found a stockpile of guns and ammunition following the arrest of four ISIL suspects near Copenhagen Thursday.

The group, believed by authorities to have been recruited by ISIL to carry out attacks, will appear before a judge at a hearing on Friday.

“We know that people who have fought for IS in Syria or Iraq may pose a specific security threat against Denmark,” said the country’s Justice Minister Søren Pind in a statement shortly after the arrest.

Danish intelligence service PET announced in October that more than 125 people from the country were believed to have traveled to Syria and Iraq to join ISIL. Estimates are that 27 of them were killed there.
